- Less Developed - Primary Economic Activities
Stage 2: Industrializing - High Birth/Rapidly Decreasing Death
- Newly Industrializing - Transition from Primary to Secondary Economic Activities
Stage 3: Industrialize - Rapidly Decreasing Birth/Low Death
- Newly Industrializing - Mostly Secondary Economic Activities, Emergence of Tertiary Economic Activities
Stage 4: Post-Industrial - Low Birth/Low Death
- More Developed- Mostly Tertiary Economic Activities, emergence of Quaternary Economic Activities
